its at the very end on the Futa on Futa path and the netori route after the update ends it mentions her and the mcs stories are spiralling apart even if Hana does not meet Natalie Andrea or Lena which i thought was a bit odd which is why i originally thought it was because scarletgames decided not make a difference update ending depending on the route which is fair if soWhere does it say Hana and Milly grow apart in the netori path?
If it's in the closing notes of netori path then you can assume it was probably a mistake / copy pasta thing. There might be some developments and decision that could lead hana away in future but right now there are no hints at all for hana to grow apart from Milly.
